Caltech cosmologist Ranga-Ram Chary thinks he may have found evidence of a parallel universe.In a new study, published in the Astrophysical Journal, Chary suggests cosmic bruising — one universe bumping up against another universe — could explain an anomaly he found in the map of the cosmic microwave background.
Researcher found while mapping cosmic microwave background was evidence of a “multiverse,”
Ranga-Ram Chary, a researcher at the European Space Agency’s Planck U.S. Data Center at the California Institute of Technology, said in a paper there was a chance that fluctuations he found while mapping cosmic microwave background was evidence of a “multiverse,”.
The idea of a multiverse, which builds on the notion of cosmic inflation, has been getting more notoriety but no one has been able to prove that other universes exist.
“The properties of our observable universe have recently been characterized in unprecedented detail through analysis of the cosmic microwave background ?uctuations, a relic of the hot Big Bang,” wrote Chary in research published in the Sept. 30 edition of the Astrophysical Journal.
“The ?ne tuning of parameters in the early universe required to reproduce our present day universe suggests that our universe may simply be a region within an eternally in?ating super-region. Many other regions beyond our observable universe would exist with each such region governed by a di?erent set of physical parameters than the ones we have measured for our universe,” said Chary.
Chary said that the fluctuating glow he found could be matter from a neighboring universe “leaking” into our universe, according to New Scientist magazine, adding that such a multiverse could be the consequence of cosmic inflation, which theorizes that the early universe expanded exponentially in the slimmest fraction of a second after the Big Bang.
Other researchers, believe the signs Chary spotted could be light of early hydrogen
“This signal is one of the fingerprints of our own universe,” said Jens Chluba, of the University of Cambridge. “Other universes should leave a different mark.”
Chary’s theory about alternative universes could be hard to prove since the Planck telescope provides limited data for additional study and it cannot measure the spectral alterations needed to advance the discovery.
“Unusual claims like evidence for alternate universes require a very high burden of proof,” said Chary.
A cosmologist from the California Institute of Technology (Caltech) believes he may just have found proof that an alternate and parallel universe does indeed exist.
In a study featured in the Astrophysical Journal, researcher Ranga-Ram Chary described evidence of a cosmic bruising, or the bumping of one universe against another, which could be used to identify an anomaly he discovered on the cosmic microwave background map.
Cosmic Microwave Background
Considered to be a remnant from the Big Bang event, the cosmic microwave background consists of the light that was formed from the chaos of the new universe’s birth.
Chary created a map of this cosmic phenomenon using data collected from the European Space Agency’s (ESA) space telescope Planck. He then compared his map with that of the entirety of the night sky after which he discovered what seems to be a blob made of bright light.
Bursts of ancient light have long been observed from the cosmic microwave background. Scientists have used these light signatures to identify traces of radiation in the universe believed to have been formed during the first hundred thousand years following the Big Bang event.
Researchers believe the ancient light itself has likely been formed from a recombination, which was when particles of protons and electrons first came together to constitute the element of hydrogen in the universe.
With the range of visible light from hydrogen severely limited, scientists use this to determine the specific colors of the ancient blobs observed in the cosmic background.
In Chary’s model of the cosmic background, however, the blob had a different color from what it should have. He said that this phenomenon could be explained through the use of a multiverse theory.
“Our universe may simply be a region within an eternally inflating super-region,” the Caltech researcher wrote.
Multiverse theorists argue that the continuous expansion of the universe has produced various pockets of energy which ended up expanding at a much faster rate and created several other pocket universes of their own.
Some scientists pointed out that this theory of cosmic inflation, or the ancient universe’s rapid expansion, lends itself to the plausibility of a multiverse.
MIT researcher and inflation theory advocate Alan Guth said that most versions of the inflation concept result in an eternal inflation, leading to many other pocket universes being created.
While the idea of multiple and parallel universes is supported by a number of well-known cosmologists and astrophysicists, other scientists choose to dismiss the possibility, calling it more philosophy or science fiction than actual science.
Opponents of multiverse theories argue that the essence of empirical science does not allow such theories to be proven or disproven.
Meanwhile, other experts in the field seek a common ground on the debate.
Princeton researcher David Spergel said that alternative possibilities should also be looked at, such as the complicated properties of foreground dust, which could offer a more plausible explanation for the ancient light.
Chary also tried to explore other possibilities, but he said he decided against them because his ideas would likely be heavily scrutinized.
